Consumer surplusIt's consumer'sNet income

Consumer surplus refers to the difference between the maximum price that consumers are willing to pay for a certain amount of a certain commodity and the actual market for those goods. Marshall from marginal utility.

The theory of value deduces the concept of consumer surplus. Van Ryan proposes several methods for calculating the surplus of pi which is the consumer. Consumer surplus is an important indicator of consumer welfare and is widely used as an analytical tool.

The social welfare of the industry is equal to the surplus of consumers and the surplus of producers.

or equal to the total consumption utility and production cost.

difference. In 1977 Dixit and Stiglitz would have built-in economies of scale.

The general equilibrium model was introduced, and the conclusion that the market considers the most modest marginal profit and the society considers the consumer surplus. It is generally accepted that the condition for the maximum consumer surplus to be reached is that the marginal utility is equal to the marginal expenditure.

Notes on consumer surplus:

There are two things to keep in mind when understanding consumer surplus:

First, consumer surplus is not an increase in real income, but a psychological feeling.

Second, there is a large surplus of consumers of daily necessities. Because consumers have a high evaluation of the utility of such items, they are willing to pay high, but the market for such items is generally not high.

Consumer surplus, also known as the net income of the consumer, refers to the difference between the maximum total ** that a consumer is willing to pay when purchasing a certain quantity of a certain good and the total ** that he actually pays. Consumer surplus is a measure of the additional benefits that buyers themselves perceive to receive.

Under the condition of voluntary trading, consumers can improve their situation by choosing the optimal amount to consume. With the help of the consumer demand curve derived above, it is a good illustration of how to measure the benefits of economic exchange.

First, start by changing your understanding of the consumer demand curve. The demand curve not only represents the relationship between the demand for goods and the quantity of goods, but also can be understood as the most expensive price that consumers are willing to pay when buying a specific quantity. But for consumers, the market is a given, so there is a difference between what they are willing to pay and what they actually pay, which constitutes a"Psychological surplus"。

The difference between the amount that a consumer is willing to pay for a certain quantity of a certain good and the amount that he actually has to pay is called the consumer surplus.

The total consumer surplus can be expressed in terms of the area of the triangle below the demand curve, above the line and on the axis.

It can be known from the surplus of consumers:

First, if ** rises, the consumer surplus falls, and conversely, if ** declines, the consumer surplus rises;

Second, if the demand curve is flat, the consumer surplus is 0.

For example, the ticket price of a movie is 20 yuan, but the value of the consumer to it is 50 yuan, so the consumer has the remaining 30 yuan. If you want to respect the preferences of buyers, then consumer surplus is a good measure of economic well-being.

The concept of consumer surplus is proposed to tell each and every one of us that we always give less than we get. We always get additional benefits in trading, and the total welfare of our society is always growing in trading.

The impact of monopolies on consumers.

Illustration of the calculation of the consumer's surplus.

Consumer surplus was first proposed by Marshall in his theory of ** and refers to the difference between the maximum total ** that a consumer is willing to pay when buying a certain quantity of a certain good and the total ** that actually pays.

b Consumer surplus, also known as net income of consumers, refers to the willingness of consumers to purchase a certain quantity of a certain commodity.

The maximum total price to be paid.

The difference between the grid and the total ** actually paid. Consumer surplus is a measure of the additional benefits that buyers themselves perceive to receive. Example:

If you don't know that this dress is **, you are willing to buy it for 200 yuan, but you can buy it for only 150 yuan, and you will feel that it is so cheap and earn 50 yuan.

As a result of the decrease in consumer spending, the products produced by the factories cannot be sold, the workers are in a state of loss, the factories are unable to pay wages or lay off workers, and unemployment increases. Unemployment increases, incomes fall, and consumer spending decreases, creating a vicious circle. So when the economy is booming, the unemployment rate is lower, the products are abundant, the ** is cheap, and everyone has money to spend.

Due to the great abundance of products, the supply of products in factories will exceed demand, and the price will be reduced, and some will reduce production. But the demand is still increasing, and finally slowly as the inventory decreases, **start**. The money in people's hands is slowly decreasing, and some of them have begun to borrow money to consume, ** have begun, and consumer spending has begun to decrease in agitation.

The economy entered a recession, and after a period of depression, it began to expand again, and slowly prospered again, and the economy went through four cycles, recovery, prosperity, recession, and depression, just like spring, summer, autumn and winter, and so on.

Some of the consumption expenditures of one person are the income of another person, and if the consumption expenditure decreases, the income of some people will decrease, and the income will decrease, which in turn will lead to a decrease in consumption. In the end, production shrinks or the goods produced are squeezed, and they cannot be sold.

The modern economy generally uses credit overdraft consumption to increase domestic demand, if moderate, it is conducive to economic development, however, excessive overdraft consumption is harmful to the economy. Because credit has a cycle, let's take a family consumption as an example, if a family starts to have no money to spend, the bank gives a limit of 100,000 yuan, he consumes the 100,000 yuan a year ago, and in the second or third year, in order to repay the debt, he no longer consumes excessively. Because the factory saw the increase in consumption in the first year, it felt that there was a market and would increase production, but in the second and third years, the factory produced a lot of goods, and because people had no money to consume, they could no longer spend through borrowing, and the income was used to pay off debts.

So it leads to overproduction. This kind of product is relatively in surplus, and some products are in short supply, such as daily necessities, food. That's why when the economy is in crisis, the food and vegetables in the supermarket are snapped up.

Maybe the car, or some mid-to-high-end goods, can't be sold. Factories will go out of business,
